Malignant hyperthermia is a life-threatening pharmacogenetic disorder triggered by certain anesthetic agents, characterized by hypermetabolism, muscle rigidity, and rapid temperature elevation. The primary nursing concern is early recognition and immediate treatment to prevent fatal complications. Key signs include: rapid rise in body temperature (may increase 1-2°C every 5 minutes), muscle rigidity (especially jaw stiffness), tachycardia, tachypnea, cyanosis, and arrhythmias. Immediate nursing interventions include: discontinuing triggering agents (volatile anesthetics, succinylcholine); administering dantrolene sodium (specific antidote) as ordered; providing 100% oxygen; implementing active cooling measures (ice packs, cooling blankets, chilled IV fluids); monitoring arterial blood gases and electrolytes (especially potassium and calcium); and preparing for possible acidosis correction with sodium bicarbonate. Documentation should include time of onset, interventions, and response. Post-crisis, patients require ICU monitoring for recurrence. Patient education includes wearing medical alert identification and informing all healthcare providers about the condition to prevent future episodes.
